“…The reason for this reduction is decreasing in penetrating of photons in dye solution due to increase in UV absorption by dye solution. These results corresponded with the results of this study (26,(41)(42)(43).…”

“…The use of PILCs in AOPs as a catalyst that helps in the degradation of organic contaminants has been frequently reported in the literatures (Sze Nga Sum et al 2004, Li et al 2006, Molina et al 2006, Ayodele et al 2012, Galeano et al 2014. The most frequently used polymeric compounds as pillaring agents are Al, Ti, Cr, and Fe (Bouras et al 2002, Dvininov et al 2009, Banković et al 2012, Sahel et al 2014.…”

AbstractIn the past few years, there have been many researches on the use of different types of homogenous catalyst for the degradation of textile wastewater in conventional advanced oxidation processes (AOPs). However, homogenous AOPs suffer from few limitations, including large consumption of chemicals, acidic pH, high cost of hydrogen peroxide, generation of iron sludge, and necessity of post-treatment. Therefore, recently, there have been more researches that focus on improving the performance of conventional AOPs using heterogeneous catalysts such as titanium dioxide, nanomaterials, metal oxides, zeolite, hematite, goethite, magnetite, and activated carbon (AC). Besides, different supports such as AC that have been incorporated with transition metals and clays have been proven to have excellent catalytic activity in AOPs. This paper presents a comprehensive review of advances and prospects of catalytic AOPs for the decontamination of a wide range of synthetic and real textile wastewater. This review provides an up-to-date critical review of the information on the degradation of various textile dyes by a wide range of heterogeneous catalysts and adsorbents. The future challenges of AOPs, including chemical consumption, toxicity assessment, reactor design, and limitation of catalysts, are discussed in this paper. In addition, this paper also discusses the presence of ions, generation of by-products, and industrial applications of AOPs. Special emphasis is given to recent studies and large-scale combination of AOPs for wastewater treatment. This review paper concludes that more studies are needed for the kinetics, reactor design, and modeling of hybrid AOPs and the production of their corresponding intermediate products and secondary pollutants. A better economic model should also be developed to predict the cost of AOPs, as the treatment cost varies with dyes and textile effluents.

“…The enhancement of the removal efficiency was due to the increase of active sites available for the photo-Fenton catalytic reaction as the loading of Fe-TiO 2 increased up to the optimum value; higher values, instead, gave rise to more important phenomena of light screening and scattering, decreasing the penetration depth of the light into the suspension [28][29][30]. Consequently, the overall number of photons reaching the photocatalyst surface decreased as well as the number of photo generated active sites producing •OH radicals by decomposition of H 2 O 2 molecules [31].…”
